SSO login use email of already logged in user

If you use DocuSign (sign of documents) with sso login and you are already logged in. With enabled Part11 module there are some points to reauthenticate. 

At moment a user always need to input it’s email address and then to decide if to use classic login or to use company login. The IDP (sso) is always asking the email + password again. That is very time consuming and frustrating for the users, always type in the email twice.

DocuSign should recognizes the email address of an already logged-in user and only ask of use classic login or use company login and forward to configured sso IDP without request for email first (only if the user is already logged in).

Please consider that enhancement.
